Abstract
An image forming apparatus is included of a pivotally rotated photosensitive drum, a developing roller for developing an electrostatic latent image formed on this photosensitive drum, and an intermediate transfer belt for temporarily holding the toner image which has been developed to be formed by the developing roller. This developing roller is equipped with a tracking roller which abuts against the photosensitive drum so as to keep a distance between the developing roller and the photosensitive drum as a constant distance. A direction of weight 'a' produced by this tracking roller with respect to the photosensitive drum may be positioned within a so-called 'wrap range' corresponding to an abutting range between the intermediate transfer belt and the photosensitive drum.
